Dense fog has taken over the Willamette Valley again for tonight. Visibility is less than a quarter mile in spots and we might see some areas drop down to freezing tonight, making for some icy roads as you head to work in the morning.

The Air Stagnation Advisories for the valley has been extended through Thursday afternoon while the Umpqua Basin have been extended through Monday morning. Thursday night into Friday, a more sizeable storm blows through the state bringing showers overnight into Friday morning. The mountains will finally see some good (albeit brief) snow as snow levels will drop to 4500 feet, but not much accumulating snow for ski resorts and at Pass level. By the weekend, high pressure again rebuilds and we’re back to sunny skies at the coast and mountains and likely more valley fog. Highs both Saturday and Sunday may struggle to get out of the 30s and overnight lows (with some colder Canadian air) will likely dip into the upper 20s, making for some slippery roads in the morning hours.

Next week, we might actually get back to a more typical winter forecast, some bigger storms starting to move through the Northwest, bringing some much needed snow for the mountains and rain showers at the lower levels both Tuesday and Wednesday.
